SPECIFICATION forming part of Letters Patent No. 351,939, dated November2, 1886. Application filed November 11, 1885. Serial No. 182,457. (NomodeLi -T all whom it may concern:

Be it known that I, OTTO LOUIS SonAsrEY,

of the city, county, and State of New York, have invented certain newand useful Improvements in Sewing-Machines, of which the following is afull, clear, andexact descrip tion. I

This invention relates to improvements in that class of sewingmachinessewing with a single thread and used for making a cross or bindingstitch.

The object of my invention is to provide certain new and usefulimprovements in the sewing-machines for which United States LettersPatent No. 328,816 were issued to me on the th day of October 1885.

The invention consists in a machine of the above-described kind havingits throat-plate made movable with the other parts, as will be describedand set forth hereinafter, and

then pointed outin the claims,

Reference is to be had to the accompanying drawings,formingpart of thisspecification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional plan view of my improved sewing-machine. Fig. 2is a front view of part of the same By means of cog-wheels or othersuitable power-transmitting devices the sleeve I is revolved from themain shaft A,which sleeve is held loosely on the shaft B,held on thebracket 0 on the base of the machine, and the said sleeve is providedwith the cam D, which acts on the sliding collar E, mounted on the mainshaftito slide, and which is connected indirectly with the lower end ofthe lever F,having its other end connected with the needlebar guidepivoted to swing laterally,as shown in the Patent No. 328,816. Thelooper B is also mounted-on the end of the sliding rod J in the tubular1113111 shaft, as set forth in the Patent No. 328,816, and which rod isalso operated from the collar E.

D, and .means In the said Patent No. 328,816 I have providedathroat-plate having two slots for the needle, which throat-plate isfixed. I now provide a throat-plate, M, which is movable and providedwith a single needle-slot,N-. Said throatplate,M is below thesewing-plate 0, over which the cloth is passed,and is secured to andprojects from one end of the rod P, havingits other end in the socket Q,projecting from the ring R, surrounding the collar E on the main shaft,whereby the said throat-plate is reciprocated so that its position willat all times correspond with that of the needle and looper.

Having thus described I claim as new, and desire to secure by LettersPatent, is-

1. In a sewing machine, the combination, with the main shaft and thestitch forming mechanism provided with a loose collar and means forsliding said collar, of a rod connected to the said collar and a slottedthroatplate on the said rod, substantially as herein shown anddescribed.

2. In a sewing-machine, the combination, with the main shaft A and thestitch-forming mechanism provided with the sliding collar E and ringB,surrounding the collar, the shaft B, provided with the sleeve I,having the cam for operating the shaft B from the shaft A, of the rod P,connectedto the ring. R, and the throat-plate M. secured to the said rodand provided with the slot N, substantially as herein shown anddescribed.
